IO_OBJECT_INVALID
Invalid kernel I/O object
IO_OBJECT_INVALID is bug check code 0x00000148. The built-in table identifies it as IO_OBJECT_INVALID
; the useful diagnostic question is what Windows component raised the stop and which invariant failed.
This bug check points to I/O manager object misuse: a driver used, referenced, completed, or passed an object whose type, lifetime, state, or ownership did not match the required contract.
How to read the parameters
- The object address and stack are more useful than the numeric code alone.
- Look for device objects, file objects, IRPs, and completion paths that outlive their valid lifetime.
- It can be exposed by surprise removal, cancellation, cleanup, close, or power/PnP transitions.
What to check in the dump
- Use Driver Verifier with I/O verification for the suspected driver.
- Inspect reference counting, cancel routines, remove locks, IRP completion ownership, and teardown paths.
- Check whether a filter driver reused an object after lower-driver completion or device removal.
